Although I followed your instructions posted on 1/19/2008 and I uninstalled ports, then restarted computer, the ports still do not recognize any device I insert in the port (it started recognizing one flash drive then it stopped). I went to device manager and each port is reported to working properly! What is wrong?

1 Connect your flash drive to your computer using an available USB port. If your flash drive is not recognized, you'll usually receive an error that says "USB Device Not Recognized."
2 Click "Start" > "Control Panel" and open the system configuration by double-clicking the "System" icon.
3 Navigate to the "Hardware" tab and click the "Device Manager" button to open the Device Manager.
4 Click the "+" next to "Disk Drives" and locate your USB flash drive. A question mark icon should be shown to the left of the label. Right-click the device name and select "Uninstall."
5 Open the "Action" menu at the top of the Device Manager and select "Scan for hardware changes." This will scan your PC for any new devices. Because you uninstalled the flash drive, it will be detected as a new device and the drivers will be reinstalled.
6 Click "Start" > "My Computer" and look for your flash drive. If this process was successful, your flash drive should now show up under My Computer as a storage disk.
Hope the above information will be helpful to you. Thanks.
